[SWFans.net]

I like the array set up of this one over how the other hot link prevention hack functions, but this hack just doesn't work for me, even with no firewall. No matter what, I get the echoed text I added so I could see what was going on.

PHP Code:

$referers = array ('www.sw-fans.net','sw-fans.net','swforums.net','www.swforums.net'); 

function check_referer($referers){ 
   if (count($referers)){ 
      $found = false; 
      for ($x=0; $x < count($referers); $x++){ 
      $temp = explode('/',getenv("HTTP_REFERER")); 
      $referer = $temp[2];
         if (ereg ($referers[$x], $referer)) { 
            $found = true; 
         } 
      } 
      if (!$found){
      echo "No hot linking allowed"; 
      exit;
      } 
         return $found; 
      } else { 
         return true;
   } 
} 

check_referer($referers);
